The first organomediated asymmetric 18F fluorination has been accomplished using a chiral imidazolidinone and [18F]N‐fluorobenzenesulfonimide. The method provides access to enantioenriched 18F‐labeled α‐fluoroaldehydes (>90 % ee), which are versatile chiral 18F synthons for the synthesis of radiotracers. The utility of this process is demonstrated with the synthesis of the PET (positron emission tomography)
首次有机介导的不对称18 F氟化反应是使用手性咪唑啉酮和[ 18 F] N-氟苯磺酰亚胺实现的。该方法提供了对映体富集的18 F标记的α-氟代醛(> 90%ee),它们是用于合成放射性示踪剂的通用手性18 F合成子。PET(正电子发射断层扫描)示踪剂(2 S,4 S)-4- [ 18 F]氟谷氨酸的合成证明了该方法的实用性。
